Assume thаt а develоper hаs already designed the fоllоwing layout, which includes three radio buttons to select a pizza size, along with a TextView to display the corresponding pizza size price as a total amount. In the layout, the three radio buttons have been assigned the IDs "small_size", "medium_size", and "large_size", while the ID of the TextView to show the total amount is "tv_total", with an initial text of "$0.0". When the user selects a pizza size, the corresponding amount should be shown in the TextView, as shown below. Based on these specifications, write the necessary Kotlin code to implement this functionality. Note: You can assume that the code will be written in an Activity and the initial setup and boilerplate code provided by Android Studio will be present. image_2025-03-11_235438952.png
